Aisle 650

Alan,

The AIS650 will remain in silent mode if its internal GPS receiver is unable to acquire a GPS position FIX using the passive GPS antenna supplied with the AIS650. The passive antenna cable should be inspected to ensure that it is undamaged and has been interfaced to the AIS650's GPS antenna socket. The AIS650's passive GPS antenna must be installed/located where it will be afforded an unobstructed view of the skies overhead.

The AIS650 will also remain in silent mode if the Silent Mode leads of the AIS650 are shorted (i.e. creating a closed circuit). Correspondingly, it is recommended that the AIS650's Silent Mode leads be inspected to ensure that any exposed conductors have been clipped off and that insulation, shrink wrap, etc. has been applied to these leads to prevent shorting. If so, then and then it is recommended that a PC running the ProAIS2 AIS650 programming/diagnostics be connected to the AIS650 and that its GNSS Status tab be inspected to ensure that its internal GPS receiver has acquired a GPS position FIX.
